So yesterday I opened up Halo 4 after work and dug right into the campaign. I beat the first two levels and then a friend of mine asked if I wanted to play some slayer, so we did that for a while. When we were finishing up our play session, we were saying that we should try out Spartan Ops the next time we were both on.
My question is, will playing Spartan Ops before finishing the campaign ruin any of the main story? Would it be best to finish up the campaign before playing that mode, or are they separate enough that it does not matter?
